EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 510,362, dated December5, '1893. Application filed September 12, 1893. Serial No. 485,338. (Nomodel.)

To all whom it may concern:

Be it known that I, JACOB POGODZINSKI, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Extension-Tables;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in extension tables of that classwhich employs a vertically-adjustable, solid, central tabletop andsliding leaves which are designed to be folded beneath the solid tabletop or to be extended in line therewith to increase the area of thetable-top; and the objects in View are, first, to provide convenientmeans on each sliding leaf whereby the end of the table-top adjacent tothe section can be conveniently elevated a sufficient distance for thesliding leaf to pass beneath the table-top, and, secondly, to provideimproved means for guidmg the table top in its vertical play or movementand for limiting the inward movement of the sliding leaves; the wholebeing so combined and organized that the table presents a neatsymmetrical appearance both when the leaves are folded beneath the topand extended flush therewith.

With these ends in view, my invention consists in the novel constructionand combination of devices as will be hereinafter fully described andclaimed.

To enable others to understand my invention, Ihave illustrated the samein the accompanying drawings, forming a part of this speci-.

fication, and in Which Figure 1 is a side elevation of the table showingthe leaves folded beneath the top. Fig. 2 is a similar view of the tablewith the leaves unfolded in line and flush with the top to increase theareaof the top surface. Fig. 3 is a longitudinal sectional view throughthe table, with the leaves extended, showing one of the levers, N,partially depressed and liftlng one end of the table-top sufficientlyfor one of the leaves to slide beneath the same. Fig. 4 is a bottom planView of the table-top, showing the relation of the leaves and the slidesthereto by dotted lines. Fig. 5 is a plan view of the table frame withthe top omitted.

I will now proceed to a detailed description of the preferred embodimentof myinvention, reference being had to the accompanying drawings, inwhich like letters of reference denote corresponding parts in all thefigures.

A designates the table frame which consists of the side rails or and theend rails b which are securely united to the legs B, the whole forming asubstantial structure. In the end rails 17, b, of the table frame Iprovide the four notches c, c, and c, c, the notches c, c, in one railbeing arranged out of line with the notches c, c, in the other rail; andsaid end rails b,b, are further provided with the notches d, d, formedcentrally thereon, for a purpose hereinafter referred to.

To the rails of the table frame is secured a false top 0, which lies asuitable distance below the upper edges of said rails, and below thisfalse top is provided a series of drawers D,which are sustained bysuitable guides below the false top so that they can slide in and outfrom the sides of the table, but the arrangement of the drawers is notmaterial, as they can be placed to slide beyond the ends of the table.

Across the top of the table frame I provide a central bar E which issecured tothe side rails or of the frame in any secure manner and whichserves to strengthen the frame, as the guide for the table top in itsvertical movement, and to sustain the pressure or strain on the leaveswhen they are extended flush with the table top. This transverse fixedbar is provided at its ends with dove-tail projections e, e, and to thelower edge of this barE is fixed the guide strips 6, e, situated inproper relation to the grooves or notches c, c, and c, c, in the endrails b, b, of the table frame.

F is the table top which is made of a single piece, or of a series ofpieces properly united together to form a solid top, which is of suchsize that it will cover the table frame when the leaves are foldedbeneath the same.

The table top F is provided near the sides thereof with the dependingguide-stops G, G, which serve the double purpose of affording a guidefor the table top in its vertical adwhereby the table top is guided inits ver-' tical adjustment and held from displacement on the table framewhile at the same time the projections e fit in the grooves g in amanner to permit the top F to have a slight tilting movement which isnecessary when only one leaf is extended beyond or shoved within one endof the table top.

In addition to the guide pieces G which coact with the ends of thetransverse bar E, I provide a depending guide-pin H which is rigid witha shank it that is fixed to thebottom side of the table top, and thisguide pin plays freely in a socket H formed in the transverse bar E andprotected by a Wear plate It suitably fastened to the transverse barover the socket therein.

The sliding leaves I, K, of my table are designed to be folded beneaththe table top F to lie flush therewith or to be extended in line withsaid table top and flush with the same in the manner shown by Figs. 1and 2, respectively. The leaf I is provided with the sliding bars J, J,which are fixed or rigid with the leaf so as to slide therewith. Thesebars are provided with the bevels or inclines j, J, on their lower andupper edges and at their inner and outer ends, respectively, so that theleaf I will be elevated to the level of the top F when it is drawn outand be depressed below said top as it is shoved beneath the same to foldthe table. These bars J, J, are fitted in the grooves c, c, of the endrail b, and they are made of such length that when drawn out from thetable frame with the leaf I the inner ends thereof bear beneath thetransverse bar E so that the bars J have a bearing against the end rail6 and the bar E to sustain the weight or pressure on the leaf I. Theoutward movement of the leaf I and the bars J is limited by means of astop j shown more clearly by dotted lines in Fig. 4 which is fixed toone of the bars J and adapted to strike against the end rail b, andthese bars .1 are limited to endwise movement by means of the grooves ornotches c, c, and the guide strip e on the bar E. The other leaf K islikewise provided with the slide bars L, L, which are fitted in thenotches c, c, of the other end rail 1) of the table frame, the innerends of said bars L being below the transverse bar E so that they slidein paths alongside of the bars J on the other leaf 1. These slide barsL, L, are each provided with the bevels Z, Z, on their upper and loweredges and at their opposite ends, and one of these bars L is providedwith the stop m adapted to bear against the end rail 1) to limit the outward movement of the leaf K.

To provide for the convenient adjustment of the table top F by hand wheneither leaf is to be shoved underneath the top F, I provide means oneach leaf whereby the end of the top F can be raised sufiiciently forthe leaf to slide beneath the same while at the same time this meansenables the leaf and slide bars thereon to be adjusted. This meansconsists of a lever N which is carried by the leaf and arranged to bearagainst the top F to lift theend thereof. This lever is arrangedunderneath the leaf and is connected atan intermediate point of itslength to said leaf by means of the hinge or pivotal joint 11 at theinner edge of the leaf so that the inner end of the lever is :free tobear against the bottom side of the top. The levers on the leaves I, K,are fitted in thecentral grooves (Z, d, of the end rails 12 of the tableframe, and they can move freely in said notches d, (1, when theleavesare adjusted. The levers extend nearly to the free edges of theleaves and they are formed with the finger holds n so that the leverscan be grasped when it isdesired to pull the leaves out.

This being the construction of my improved table, the operation may bedescribed as follows: With the table in the folded position shown byFig. 1, it is only necessary to grasp the ends of the levers .N and pullthe same outward, whereupon the leaves and the slide bars will be drawnout, the leavesbeing raised by the inclines on their slidebarsduringtheir outward movement and the table top F dropping upon the slidebars to be sustained thereby fiush with the leaves I, K, when the latterare extended. During the outward movement of the leaves and slide bars,the table top :IS raised with the leaves and guided bytheprojections G,G,.and the pinH. To fold one leaf of the table, the outer end of thelever N is depressed to force the inner end of the lever upward and withit the adjacent end of the top F, and when the top has been raised asufiicient distance, the lever, the leaf and the slide bars are forcedinward. During the inward movement, the slidebars depress the leaf sothat it passes freely beneath the end of the top F; and this top restsupon the leaf after the latter is folded so that the top remains flushwith the other unfolded leaf, as shown by Fig. 3. This unfolded leaf canbe shoved beneath the top in like manner by manipulating its lever N,andwhen both leaves I, K, are folded, they are flush with the edges of thetop F as shown by Fig.

tended inllne therewith, the outer edges of the leaves being likewiserounded to lie flush with the top when folded beneath the same; but thisis optional.

The outer faces of the pendent guides G, G, are made rounding or beveledat P to conform to the inner edges of the leaves I, K, and the leavesare limited in their inward movement by coming in contact with thepieces G, G, which lie in their path, the pieces G, G being finished tocorrespond with the leaves and thus preserve the symmetry of the table.I am aware that changes'in the form and proportion of parts and detailsof construe tion of the devices herein shown and described as anembodiment of my invention can be made without departing from the spiritor sacrificing the advantages thereof, and I therefore reserve the rightto make such changes and alterations as fairly fall within the scope ofthe same. 7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is 1. In an extension table, thecombinatio with a table top, of the sliding leaf provided with theinclined bars, and means carried by said leaf for lifting theadjacentend of the table top a suitable distance for the leaf to slidebeneath the top, substantially as and for the purpose described.

In an extension table, the combination of a frame having the notchedbars, a verticallymovable top guided on said frame, the leaves providedwith inclined bars, and a lever carried by each leaf to Work in thenotched bar of the frame and have the free inner end adapted to lift oneend of the table top for the leaf to pass beneath the same,-substan-'tially as and for the purpose described.

end rails, the leaves carried by the bars, and

the levers fitted in the central notchesand each fulcrumed at anintermediate point of its length to one of the leaves, whereby the innerfree end of the lever can be raisedto lift one end of the top,substantially as and for the purpose described.

4. In an extension table, the combination of a frame adapted to sustainthe drawers and having its end rails provided with the cen tral and sidenotches and the friction rollers, the inclined bars fitted to slide inthe side notches and provided with the lugs to limit their outwardmovement, the leaves fixed to the slide bars, the top having the pendentpieces G, G, arranged in the path of the leaves to limit their inwardmovement, the transverse bar fixed to the frame over the slide bars andhaving its ends fitted in the pieces presence of two witnesses.
